For quite some time, I am reading about space adhesives. Selecting the right adhesive for space applications is extremely important, mainly due to the high vacuum (around 10-8 Torr), and the variation in temperature. A key concern is the outgassing property of these adhesives. Any outgassing might lead to contamination of electronic or optical components, which can have a drastic impact on the optical properties of the system.
What are the commonly used space adhesives in satellites?
What are the standards of adhesives to qualify as space-worthy (other than Outgassing standard test ASTM E 595 / ESA PSS-014-702)?
Which would be the most important requirement or trade-off of a space adhesive (withstanding wide range of temperature / UV, gamma & other radiation / lower outgassing / resistance against free radical or atomic oxygen)?
